THORNBURGH, or LE IA, NEW JERSEY, ASSIGNOR TO AMERICAN CAN COM- PANY, OF NEW YOBK N, Y., -A CORPORATION- OF NEW JERSEY COMBINED HERMENIC AND HINGED CLOSURE CONTAINER Application filed December 1, 1924. Serial No. 753,073.

principal object the provision of a combinedhermetic and hinged closure container of economical and efiicient construction.

Theordinary hinged cover tobacco can of the flattened, pocket form permits the tobacco out too rapidly, even though waxed paper is employed to enclose the tobacco within the can and it has, therefore, been suggested to employ for this purpose ahermetically sealed container provided with a tear- ,ing strip and an interior collar, together with means for hinging a cover for use after the tearing strip has been removed. One such construction is shown in Patent #1351375, granted April 17, 1923, to John M. Hother- In the construction shown in said plemental cover is employed which entails considerable additional expense, and 1n other constructions of whlch I am aware, consider- .able diiiiculty has been experienced in satis- 'factorily hinging the cover so that it may be operated efliciently after the tearing strip has been removed. It is the purpose of my invention, therefore, to provide a combined hermetic and hinged cover container which will successfully meet the requirements in a container of this character and which may be manufactured within practical costlimits for quantity production.

An important feature of the invention is the provision of a container of the foregoing character in which the portion of the body above the tearing strip is hinged directly to the interior collar without the use of any supplemental hinge part, so that said body portion may serve as a hinged reclosure adapted to close upon said interior collar.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a perspective View of an assembled and closed pocket container in which.

my invention is embodied; 1

Fig- 2 is a plan view, partially broken away, of the body blank of the form employed in the practice of my invention, the hinge lugs being shown extended and with the pintle member disposed in the curled edge port-ions thereof;

Fig. 3 is an edge elevation of the blank v shown'in plan in Fig. 2; I c i Fig. 4 is a similar View, showing the hinge lugs bent to final position;

Fig, 5 is a plan view of the blank used i making 'the interior collar;

Fig. 6 is a sectional view, taken substantial-ly upon the section line 66 in Fig. 5 and showing the hinge lugs bent downwardly to final position;

Fig. 7 is a partial enlarged cross-sectional View of the body and collar members in the process of assembly priorto the positioning of the cover;

Fig. 8 is a similar View, showing the hing ing elements on the cover and body brought into assembled relationship; and

Fig. 9 is a perspective view of the upperportion of the container after the tearing strip has been removed and showing the hinging connection between thereclosure and the interior collar.

Upon said drawings, the reference character 11 indicates the body of the container,

which is hermetically closed by a bottom end 12 and a top end 13, the body beingformed with the usual lock and lap side seam 14. 'Encircling score lines 15 and 16 are provided in the body blank, as shown in Fig. 2, and these score lines setoff a tearing strip 17, which terminates-in a tongue 18, adapted to be engaged by a key for removing the tearing strip when it is desired to open the container.

For the'purpose of providing a hinged reclosure for use after the tearing strip has been opened, I employ an interior collar member 19 which, in the present instance, is made from a blank of the type shown in Fig. 5 and is provided with hinge lugs 21, the collar blank being cut away at 22 adjacent said lugs. Said lugs 21 are bent downwardly on the outside of the collar, as shown in Fig. 6, in such manner as to provide pintle receiving pockets 23 at the top thereof and the ends of the collar are joined together in a seam 24:, or in any desired manner.

Referring now to Figs. 2 to 4:, inclusive, it will be noted that lugs 25 are provided upon the body blank, extending upwardly from the top center thereof, there being three such lugs in the present instance and the outer ends thereof bein curled, as indicated at 26 to receive a pintle wire 27.

The lugs 25 are bent downwardly within the body, as shown particularly in Figs. a, 7 and 8, prior to the application of the top 13 to the body and the collar 19 is assembled within the body by pressing it downwardly, inthe manner illustrated in Figs. 7 and 8, with the hinge lugs 21 disposed between the collar wall and the wall of the container, said lugs being disposed between the lugs 25 and being adapted to engage over the pintle 27 toprovide a hinge connection between the top portion of the container body and the collar 19.

It will now be evident that when the tearing strip 17 is removed, a reclosure 28 (see Fig. 9) is provided, which is hinged directly to the collar 19 by means of the lugs 25, 21

and the pintle 27. Said collar 19 provides a wall upon which the flange of the hinge cover may close and an efficient hinge construction is thus provided without the use of supplementary hinge parts, or an additional cover, or other expensive or complicated means.

Inasmuch as the collar 19, in assembled position, tightly fits within the body 11 and inasmuch as the lower ends of the lugs are below the lower score line 15, the said lugs are securely held between the walls of the said collar and body and the pintle is rotatably held within the pockets 23 without the need of attachment of the lugs 21 to the wall of the collar 19. The bent portion of the lugs 25 are tightly enclosed within the seam, securing the cover 13 to the body 11, and this rigidly holds said lugs 25 against the Walls of the reclosure 28 and thus insures free hinging action.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages,

the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. An hermetic and hinged closure can comprising a cover, having in combination a body the blank of which is scored to form a tearing strip and formed with hinge lugs in one piece with the top edge of said blank, said lugs carrying a pintle and bent down on the inner side of the body, a collar inserted in the body and having hinge lugs embracing said pintle and extending down between said body and collar, and an end hermetically secured to said body, said cover belng released by the removal of the tearing strlp so that it can hinge on said pintle and fit removably around said collar.

2. A blank for the body of a hinged closure can, said blank being cut to form hinge lugs extended from an edge of the blank, and having a hinge pintle held in said lugs, and having a tearing strip set-01f by weakened lines on said blank and extending along said edge'of the blank, said lugs being adapt ed to be bent over against the body of the blank to rearrange the pintle near and parallel to said tearing strip and at the inside of the can, and leave the body imperforate.
